ITM, there's a tiny stack, #2 stack pushes, SNGPT says call with A4o

[pergesu]

Blinds 300/600
BB has 1120 before posting
Hero is SB with 3750, A4o
Button has 3130

Button raises to 1900 here, but it's effectively a push since he'll certainly call an all-in. If we say it's an all-in, SNGPT makes this a pretty easy call if the guy's pushing 13% or more of his hands, which is safe to say is true so far in this tourney. But the small stack has less than 1 BB after posting, so how could calling possibly be good with this weak of a holding?
